Summary0010326: Wrong architecture for CMAKE_SYSTEM_PROCESSOR
DescriptionCMAKE_SYSTEM_PROCESSOR returns always i386 on MacOSX 10.6.x. But running on a MacPro I expect x86_64.

Testing the output of uname:
MacBookPro:
feilung% uname -p feilung% uname -m
i386 i386
MacPro:
wanglung% uname -p wanglung% uname -m
i386 x86_64
It seems uname -p is returned, but uname -m would be nicer ...

The documentation for CMAKE_SYSTEM_PROCESSOR clearly states that uname -p is used to determine its value:

http://cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_SYSTEM_PROCESSOR [^]

In these days of universal binaries and cross-compiling, it is not meant to be used for anything other than a "best guess" about what your targets' primary architecture is going to be...

If you must have some other value, then use some other means to get it. CMAKE_SYSTEM_PROCESSOR is set to the output of "uname -p"
